Abstract (en)

[origin: EP3130853A1] A combustion chamber (16) comprises at least one annular wall (40, 42). The annular wall comprises at least one box like structure (62) and each box like structure comprises an inner wall (66), an outer wall (64), an upstream end wall (76) and a downstream end wall (78). The inner wall is spaced radially from the outer wall and the outer wall has a plurality of apertures for the supply of coolant into the box like structure. The inner wall, the outer wall, the upstream end wall and the downstream end wall are integral. The upstream end of the annular wall has features (84, 86) to secure the annular wall to an upstream ring structure (44) and a downstream end of the annular wall has features to mount the annular wall on a downstream ring structure (54, 56). The inner wall has at least one slot extending through the full thickness of the inner wall to accommodate differential thermal expansion between the inner wall and the outer wall.
